Referring to the drawings, 1 represents the frame of a truck, 2 a dumping body, 3 the tail-board for the same. Attached by bolts 4, or otherwise properly secured to the rearward end of the frame 1, is the supply box 5, having an open top and a. semi-circular bottom. At one end of the box is ahead 6, through a bearing in which is journalled the shaft 7. Fixed to the end of this shaft (7) is a sprocket wheel 8, running over which is the sprocket chain 9. The wheel 8 and the chain 9, together with the sprocket wheel which is fixed on the outer end of the truck axle 11, constitute the driving means for the shaft 7.

At the end opposite to the head 6,.the supply box 5 is supplied with a flange 12, and secured by the bolts 13, to this flange (12) is a similar flange 14 secured to the inner end of the distributing box 5. At the outer end of the box 5 is the head and in a bearing in which 15 operates the outer end of the shaft 7 Mounted on the shaft 7 is the spiral conveyor 16 and at 17 is a coupling with a squared recess made to fit the squared end of the shaft 7 A counterpart of the conveyor 16, 16', is fixed on the shaft 7 making a substantially continuous conveyor along the whole length of the interior of the boxes 5 and 5. These conveyors may be cut at intervals along the shafts 7 and 7 and bearings, not shown in the drawing, to support the shafts, placed within the boxes. Collars 18 and 19 carry the thrust of the shafts 7 and 7 against the heads 6 and 15, respectively. As will be seen, by this construction I may completely detach the distributing from the supply portion of the box.

Integral with the head 6 is a bracket 20, pivotally hung on which, over the pin 21, is the lever 22. The upper portion of this lever (22) is arcuate in form and partially surrounds the cam 23. A roll 24 pivoted on the upper end of the lever (22) operates in,

and is engaged by the sides of, the cam path 25. The cam 23 is fixed on the shaft 7, and rotation of the cam imparts to the lever 22 an oscillatory movement.

The lower portion of the lever 22'is bifurcated and each bifurcation, 26, has transverse slots 27 cut therein. Between these bifurcated parts operates the rod 28, flattened where it passes through. A pin 28 is fixed in the rod 28 and extends through the slots 27 Thus when the lever 22 oscillates there is a reciprocatory movement produced in the shaft 28 held in the bearing 29 of the hanger 30. This latter member is susceptible of a vertical movement through its pivotal connection to one arm of the bellcrank lever 31 which is pivoted to the frame 1 at-32 and has on its opposite arm pivotal connection at 33 with the reach rod 34.

Observing the Figs. 3, 4, 5, 12 and 13, 35 is an outer box secured, by the rivets or bolts 36, to the extended portions of the distributing box 5. The bottom 36 of this member (35) has numerous ports or passages cut therethrough. These ports, 37, are preferably cut diagonally so as to better distribute the sand in an even manner over the road surface. Positioned at a spaced distance above the bottom 36 is a ported slide member 38, the ports 39 likewise being cut diagonally and to match those cut in the bot tom. The slide (38) has upturned sides 38 and attached at intervals along its length are narrow plates or gussets 40 extending upwardly and having rolls 41, rotatable over studs 42, projecting outwardly and designed to run over the tracks 43 which are fixed to the inner sides of the outer box 35.

One end of the slide is bifurcated at 44 and within the bifurcation is pivoted the end of the rod 28, as seen in Figs. 2 and 4. It will thus be seen that any movement of the vehicle wheels will cause the slide 38 to reciprocate through the means of the interconnecting parts, and will have the effect of openin and closing the passages through the distri uting box 5.

In Figs. 4 and 12 this passage is shown completely out off. In Fig. 9 it is shown partially open, and in Fig. 8 wholly so.

It is very essential that means be provided to vary, at times, the quantityof sand being spread on the oiled surface of the road. To accomplish this object I employ the parts, some of which I have already -described, which are illustrated in Figs. 1, 6, 7 and 10 of my drawings. On the vehicle, near the drivers seat, are hand levers, one of which, 45, is used to actuate the tail-board 3 through the connecting reach rod 46. This will allow the driver, or an operator whose duty it is to attend solely to the feeding of the sand, to regulate the gravitation of the latter in the proper amounts from the dump-body to the supply box 5.

member is upper position, 0

The other lever, 47, to which the reach rod- 34 is pivotally attached, controls the vertical action of the hanger 30. In Fig.

10 the result of raising. or lowering the graphically shown. In its shown in full lines, the arc action, ,or one oscillation, of the pin 28' will move the shaft 28 a distance represented by the space a. By lowering. the hanger, which carries the shaft 28 with it, to the position shown in dot and dash lines this movement of the shaft 28 through one oscillation of the pin 28' will equal the space marked 6.

It is therefore possible by manipulating the hand lever 47 to produce, at thewill of the operator, a greater or lesser width of effective opening through the slide and bottom passages, with a consequent dropping of a larger or'smaller amount, respectlvely, of the sand.

Particular attention is called to the fact that the slide 38 is suspended a spaced distance above the bottom 36 of the distributin box, thus eliminating a large amount of friction otherwise existent Were they in rubbing contact, and more especially so when the properties of the material in which they areimmersed is considered. The object of placing'the ports in a diagonal fashion is to preventthe sand from falling in wind-rows on therroad surface, that is, in long streaks of sand instead of in a smooth even thickness.

As itis not always the practice to screen the sand or gravel before using it on the hi hwa s it frequently contains rocks or f y e bles'when deposited in the distributing ox. If, in the process of operating the machine, one of these rocks should become lodged in one of the ports'of the slide the positive action of the slide actuating mechanism would quite likely cause injury to some of the parts were it not for the safety device which is embodied in'the construction of the slide connecting rod 28.

By reference to Fig. 15 a sectional detail of this element will be seen. It will be noticed that the rod 28 is divided,-one of the adjacent ends 28' being enla-r ed and having a hole 48 bored therein. e other adjacent end is providedwith a collar 49, somewhat larger'in diameter than'the rod, and fixed thereto. This collar is made so that itwill be an eas sliding fit in the hole. At the outer end 0 this hole, and threaded mto it, is a bushing 50. Interposed between the collar 49 andv the bushing 50, and also between the collar and the bottom of the hole 48, are helical springs 51. These springs are set .sufliciently to hold the col-.

lar 49 in a substantially central position in the hole 48 under all ordinary working conditions. But should any obstruction be placed in the ports of the slide 38 or bottom supp] vertically of said sion is of a sufiicient amount to allow the actuating members, such as the cam 23, the

lever 22 and the rod 28 to function without the possibility of breakage of any of these parts.

So as to be more conveniently transported from place to place I have constructed the supply and distributing boxes of the machine so that the latter may be detached from the former, and by disengaging the brace rods 52, which act as outriggers for the distributing box, I am able to strip the vehicle, equipped with the sanding machine, of all cumbersome and overhanging parts for the purpose of locomotion without interfering with tralfic. These members may readily be re-assembled when the apparatus reaches the section to be sanded.

As will be apparent, after a careful reading of my s ec'ification, there may be certain features In the device which I may elect to modify in minor details, as for instance, the method of conve ing the sand from the to the distributin box. While I havefllustrated and descri ed this particular element as being in the form of a spiral or screw conveyor the function of a feed for. the sand will beequally existent and inherent in the device should I. decide to adopt chain conveyor.

general, shall not restrict me to the exact mechanical construction as hereinbefore described, andillus'trated in my drawings, but

' that I shall be at liberty to depart from this exactness in so far as any deviation therefrom'sha'll at all times conform to the s irit and intent of the invention and fall within the scope of the appended claim. 7

Having thus described my invention, what I claim 1s:

a In a machine of the class described, comiising a box, a perforate bottom member or said box, a slide having perforations therein disposed in spaced relation to and bottom member, upturned sides on said slide, a rail fixed to each side of said box hangers fixed; to and exten upwardly from the said upturned sides 0 said slide a roll revoluble on the u per end of each of said hangers, said rolls a apted to traverse said rails and to support said slide suspended from a position a spaced distance from said bottom, partitions in said box running longitudinally thereof and separating the main, interior portion from the space in which said rails and said rolls are operable, and means to actuatesaid slide.
